1 / 10 page (Preliminary) ABV8068/69 320-640MHz Low Phase Noise VCXO 30332 Esperanza., Rancho Santa Margarita, Ca 92688 Ph: 949-546-8000 Fax: 949-546-8001 www.Abracon.com 9/1/05 Page 1 FEATURES • Less than 0.4ps RMS (12KHz-20MHz) phase jitter for all frequencies. • Low phase noise output (@ 1MHz frequency offset) ∗ -140dBc/Hz for 320.0MHz, ∗ -131dBC/Hz for 622.08MHz • 20MHz-40MHz crystal input. • 320MHz-640MHz output. • PECL, or LVDS outputs. • No external varicap required. • Output Enable selector. • Wide pull range (+/-200ppm). • 3.3V operation. • Available in 3x3 QFN or 16-pin TSSOP packages. DESCRIPTION The ABV806X is a monolithic low jitter and low phase noise VCXO, capable of 0.4ps RMS phase jitter and PECL or LVDS outputs, covering a wide frequency output range up to 640MHz. It allows the control of the output frequency with an input voltage (VCON), using a low cost crystal. The ABV806X is designed to address the demanding requirements of high performance applications such as SONET, GPS, Video, etc. BLOCK DIAGRAM PACKAGE PIN ASSIGNMENT 16-pin TSSOP 3x3mm QFN Note1: ^ Denotes internal pull up resistor.
